THE PILOT STATED THAT DURING LANDING AT THE HOSPITAL HELIPORT, ABOUT 3 TO 4 FEET ABOVE TOUCHDOWN, HE FELT AN IMPACT FROM THE TAIL AREA WITH IMMEDIATE SEVERE VIBRATIONS. HE ROLLED BOTH THROTTLES OFF AND COMPLETED A LANDING FROM LOW HOVER. INVESTIGATION REVEALED THAT THE TAIL ROTOR HAD STRUCK A HELIPORT PERIMETER FENCE. THE PILOT NOTED THAT THE FENCE WAS BUILT WITH AN APPROXIMATE 4 INCH GAP AT MID SPAN. THE TAIL ROTOR GUARD ON THE HELICOPTER WAS ABLE TO SLIP INTO THE GAP, WHICH RESULTED IN CONTACT BETWEEN THE TAIL ROTOR AND FENCE.
Probable Cause: THE PILOT-IN-COMMAND'S FAILURE TO MAINTAIN CLEARANCE FROM THE PERIMETER FENCE WHILE LANDING. A FACTOR WAS THE HELIPORT PERIMETER FENCE.
